Poe is falls more in love with Finn every single day. He's kind, determined and a complete badass on the battlefield. He's also really fucking handsome. Poe thinks they're on the same page and finally summons the courage to ask Finn on a date. Finn is shocked and embarrassed and tries to let Poe down easy, because he is completely, 100% straight. And kinda in love with Rey...

Things become a bit strained after that, mostly from Poe's end.
